A song by the band blink 182 where it describes a boy who follows a girl to her house, hides in her tree day and night watching her change.
The word itself describes one who gets sexually aroused by hiding and spying on a couple ad/or 1 person who is doing somthing sexualy arousing.

The act of watching one's self masturbate feeling as an outside observer. A three step process; sit on hand to make it goe numb (see Stranger), apply a rubber band to base of ones penis (to lose personal feeling), then beat that dick like it owes you money.

Look down on occasion, you are know a voyeur!

In true "Voyeur" style, I caught a great "show" last night, some good looking dude with a HUGE dick was beating off like a monkey.
